Although the in vivo and in vitro degradation behavior of Mg alloys have been extensively explored, only a few in vivo studies on the metabolic behavior of the degradation products of different elements are available. In this study, a Mg-2 wt. % Zn-0.5 wt. % Y-1 wt. % Nd-0.5 wt. % Zr (ZE21C) alloy was used to prepare suture anchors, which were implanted into the patellar ligament proximal tibia of rats. The metabolic behavior of magnesium, zinc, and neodymium in the degradation products in vivo was analyzed through SEM, EDS, micro-XRF, and western blotting. These results indicate that Mg was rapidly metabolized and absorbed. However, Zn and Nd exhibited slow metabolic rates and accumulated as degradation products. This is mainly because the microenvironment generated by degradation inhibits metabolism by affecting the expression of cation-permeable channel proteins.

The results showed that microstructure evolution primarily underwent three stage to form the GS. In the early stage, deformation was dominated by a combination of multiple slip systems and twinning. In the intermediate stage, twins and coarse grains broke down into fine lath structures and smaller grains due to dislocation pile-ups and stacking faults (SFs). In the final stage, these fine grains were further refined into nanograins with the help of SFs. Compared with the original alloy, the introduced GS significantly enhanced the mechanical properties, and had a good work hardening capabilities. The strengthening mechanisms are primarily attributed to dislocation strengthening and grain boundary strengthening.

Yet, exotic electrolyte components forming passing layers on magnesium (Mg) surfaces usually leads to ultrahigh overpotential for reversible Mg chemistry. Here a novel self-supporting composite was constructed to address this issue by using chemically activated natural jujube wood-derived hard carbons (a-JHCs) with a three-dimensional (3D) network like skeleton as the artificial Mg-ions (Mg2+)-conducting interphase, achieving selective Mg2+ transport. Different from the traditional artificial solid-electrolyte interphase (SEI), the porous a-JHCs allows for 3D ion-conduction, thereby improving ion transport efficiency. Meanwhile, interfacial characteristics of a-JHCs have been demonstrated to suppress the intrusion of Mg deposits into micro-porous separators, allowing the Mg plating/stripping reaction beneath the interface. The artificial interface with low electronic conductivity significantly stabilizes the Mg electrode in conventional organic electrolytes. We show this proof-of-concept enables the reversible cycling of a Mg||V2O5 full-cell in the water-containing, and also opens the door to electrolytes previously considered as non-compatible with Mg.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"12 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144611339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their susceptibility to fatigue failure poses significant challenges for the long-term service under cyclic loading. This review systematically explores the precipitation behavior in the representative rare-earth containing magnesium (Mg-RE) alloys and examines the critical role of precipitates in influencing fatigue behavior. The alloying elements and heat treatment play a pivotal role in affecting the precipitation behavior of the Mg-RE alloys. Notably, the β', β'', and 14H long-period stacking ordered (LPSO) phases serve as primary strengthening precipitates in the Mg-Gd (Y), Mg-Nd, and Mg-RE-Zn based alloys, respectively. The size, quantity, and distribution of these precipitates can be finely controlled through the optimization of aging treatment parameters. Based on the fundamental principles for enhancing fatigue resistance, this review offers a detailed analysis of the effects of precipitates on fatigue behavior, addressing key aspects such as crack initiation, propagation, and fatigue failure under high-cycle fatigue (HCF) conditions. Besides, the effects of precipitates on the cyclic stress response, cyclic deformation characteristics, and fatigue life under low-cycle fatigue (LCF) conditions are systematically summarized. The influence of precipitates on fatigue behavior of Mg-RE alloys is primarily attributed to the mechanisms such as dislocation pinning, crack path deflection, precipitation strengthening, and the suppression of twinning. This review highlights the significance of precipitation behavior in optimizing fatigue resistance and provides valuable insights into future research directions for advancing Mg-RE alloys in the fatigue-critical structural applications.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"8 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144586845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the magnesium alloy stent degrades too quickly after implantation, and issues with restenosis and inadequate endothelialization have made it impossible to use it further. In this study, the corrosion resistance of magnesium alloy samples was firstly enhanced by fluorination, followed by self-assembled polydopamine coating, and finally, Exo@S-HA core-shell structured nanoparticles were immobilized on the surface of the coating by ultrasonic spraying. First, exosome fluorescence labeling, AFM, XPS, and FT-IR were used to show that the MgF2/PDA/Exo@S-HA composite coating was successfully prepared, and the good hydrophilicity of the composite coating was proved by the WCA, which is favorable for cell adhesion and proliferation.

Magnesium-based packaging systems demonstrate considerable promise in this strategic domain; however, current research efforts remain notably sparse, particularly regarding SiC particulate (SiCP)-reinforced magnesium matrix composites. In this investigation, we prepared SiCP-reinforced magnesium matrix composites through optimized stir casting methodology and systematically investigated their thermophysical characteristics. Remarkably, the composite incorporating merely 25 vol.% SiCP exhibited exceptional thermal performance metrics: a thermal conductivity of 178.5 W/(m·K) and a coefficient of thermal expansion as low as 16.8 × 10−6 K−1. Furthermore, molecular dynamics simulations were employed to elucidate thermal transport mechanisms at Mg/SiC interfaces, revealing that chromium interlayer implementation substantially enhances interfacial thermal conductance compared to direct bonding configurations.

Herein, a heterogeneous Mg-0.6Al-0.6Mn-0.5Zn-0.2Ce-0.2Nd (A200-10) alloy with a high density of dislocations was obtained through low-temperature extrusion and short-term annealing. The microstructure consists of recrystallized (RXed) and unrecrystallized (unRXed) regions, with a precisely controlled volume fraction ratio of 3:1. The heterogeneous A200-10 alloy exhibits a high tensile yield strength (TYS) of ∼306 MPa and a superior tensile elongation (TEL) of ∼18.4%. Based on quasi-in-situ electron backscattered diffraction (EBSD) and scanning electron microscope (SEM)-digital image correlation (DIC) analysis, we find that plastic deformation occurs preferentially in the RXed regions, mediated by the mobile <a> dislocations. As strain increases, strain gradient gradually accumulates at the interface between RXed and unRXed regions, generating hetero-deformation induced (HDI) strengthening and hardening. Besides, there is significant intergranular slip transfer in RXed regions, which can coordinate partial strain incompatibility. Furthermore, heterogeneous interfaces play a crucial role in enhancing crack tolerance. The heterogeneous interface functions as a bridging ligament to withstand stresses, and activates non-basal slips in the unRXed grains near the crack tip. Such activation of extra dislocations not only alleviates stress concentration but also dissipates the energy essential for microcrack propagation, thus effectively blunting the crack tip. Accordingly, the heterogeneous A200-10 alloy obtains an excellent strength and elongation combination. This work is anticipated to provide a valuable avenue for the development of Mg alloys with outstanding performance by regulating the appropriate heterostructure.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"74 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144565881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
